I used the ATMega32 until my projects needed more flash/SRAM then I went to
the ATMega1284.

For DIY projects go for the largest memory processor with the most features
unless you are really short of funds, power (i.e.: battery, etc.), or board
space.  The cost difference in processors is minor and it can be frustrating
when you "outgrow" a smaller processor and have to stop software development
or can't fit in that next cool feature until you order the bigger processor
and get it mounted ...

Probably not directly applicable to your case and involves specialized
communications, but, In my main project (ride-on scale railroad signal
system, about 16 nodes installed so far) I went with the ATMega32 (later
ATMega1284) and an external CAN controller because I had never used CAN
before.  I made the PCB with an option to go with RS-485 if the CAN had not
worked out.  CAN has worked so well that I wish I had used the ATCAN128,
etc.  It would have been a lot easier to interface (I have to use SPI to
talk to the external controller) and taken up less board space.
